WATER-RESERV 01R FOR RANGES.

To all whom it may concern;

Be it known that I,,Lorn Seances, a citizen of the United States of America, residing at the city of St. Louis, State of Missouri, have invented a certain new and use ful Water-Reservoir for Ranges, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to, the accompanying drawings,. forming; part of this specification.

- My invention relates. to water; reservoirs for ranges. and,v more particularly, to reservoirs adapted to be used in connection with coal ranges.

One of the objects of my invention is. tov so construct a water reservoir that it will have a contact panel or face which will yield to compensate for any irregularities in the parts. of therange and reservoir holder so that all, sides of the contact faceor panel may be brought into close contact with the corresponding face of the range.

Another object of my invention to so construct the contact face or panel that the said face or panel will be prevented from buckling away fromthe corresponding face of the range.

My invention also consists, in certain other novel features and details of construction, all of which willbe describedin the following specification and pointed out in the appended claims.

In the accompanying drawings, which illustrate one form of reservoir made in accordance with my invention, Figure 1 is a perspective view of the complete reservoir; Fig. 2 is a sectional view showing a detail of construction; Fig. 3 is a vertical section through the reservoir, together with its housing and the portion of the range to which it is attached; Fig. 4: is a sectional view showing a detail of construction; Fig. 5 is a perspective view showing the bottom and two sides of the reservoir; Fig. 6 is a perspective view showing one end of the reservoir; and Fig. 7 is a horizontal section through the reservoir before the lap seams are bent over.

Like marks of reference refer to similar parts in the several views of the drawings.

The reservoir, which isperfectly formed of sheet copper, consists of a bottom 10, a rear side 11, a front side 12, and two end Specification of Letters-Patent.

pieces 13. The rear side 11 is vertical for only a portion of its length and then is inclined inwardly at 14. The edges of the bottom and sides are turned over, as indicated at 15, so as to receive corresponding flanges 16 formed on the end pieces 13. After the flanges 16 have been inserted between the bottom and sides and their turned over portions 15, as shown in Fig. 7, the seams are hammered over, as shown in Fig. 2, so as to form; a lap joint which will be perfectly water-tight when soldered. It will be evident that, by this construction, I avoid the loss of any metal in forming the reservoir and, at the same time, reduce the amount of lap seaming and soldering to, a, minimum. The. rear side-.11 is to be drawn into contact with the face of the range bymeans which will be hereinafter described. I have found that, in the practical. manufacture of the range; and the housing for the reservoir, certain irregularities are bound to occur. In order to compensate for; these irregularities, I form the face 11 with a contact panel 18 which is struck up over the said face and occupies. nearly the entire surface. thereof, only a small margin being left around the, panel 18. This panel 18 is connected with the face 11 by a portion of. metal 19 in the form of an ogee curve. I, have found that, by making this portion 19 about one-eighth of an inch in height, the resiliency furnished by this portion, together with a slight strip of metal forming the remainder of the face 11, will be sufficient to compensate for the irregularities in the parts above referred to so that the four sides of the contacting face may be drawn up into close contact with the corresponding face of the range. I have found, however, that even when all four sides of the contacting metal are brought into close contact with the face of the range, there is a liability of the contact face buckling away from the face of. the range and thus making imperfect contact so that the water in the reservoir will be heated but slightly. In order to overcome this difficulty, I make the outer face of the contacting panel 18 slightly convex, as best shown in Figs- 2 and 7 of the drawings. This convexity, it will be understood, is in both the transverse and longitudinal sections of the panel. I find that when a panel of this form is drawn firmly against the face of the range it assumes a plain form, as shown in Fig. 3 of the drawings, but the tension under which the metal is held, owing to its original concave form, is such as to prevent any buckling of the metal away from the face of the range. In order to hold the face 18 of the reservoir against the range, I provide a housing consisting of a top 20 having projecting portions 21 adapted to engage with openings 22 in the top 23 of the range. Secured to this top 20 is the body 24 of the housing. This body 24: is secured to the top 20 by means of bolts 25 engaging with the lugs 26 on the top 20 and lugs 2'7 carried by the said body 24 of the housing. The bottom 28 of the housing is preferably secured to the body 24 by a lap joint 2- The bottom 28 of the housing is formed of sheet metal and formed integral with it a re stop plates 30 engaging with the ends 13 of the reservoir and the stop plate 31 engaging with the front 12 of the reservoir. In order to draw the reservoir into contact with the face 32 of the range, I provide a rock shaft 33 joined to bearings 34: carried on the bottom 28 of the housing and having an end 35 engaging with a cam 36 carried on the side 32 of the range. This rock shaft and cam are similar in form and operation to the rock shaft and cam described in my prior Patent No. 1,063,944, granted June,

an opening 38 for the passage of the rock The rock shaft 33 is provided shaft 33. with a handle 39.

The operation of my device will be evident. By turning the rock shaft 33 by means of the handle 39, the housing and,

consequently, the reservoir, may be moved either into or out of contact with the face 32 of the range. As has been previously pointed out, theconstruction of the contact Copies of this patent may be obtained for panel 18 is such that it yields to compensate for any inequalities in the range or the housing and, consequently, the panel is drawn up with all four sides in contact with the face of the range regardless of such inequalities in the parts. Furthermore, the convex form of the face of the panel 18 prevents any possibility of the said face buckling away from the range and, consequently, a perfectly tight contact is maintained at all times.

Having fully described my, invention, what I claim as new and desire to secure by LettersPatent of the United States is:

1. A water reservoir for ranges having a side adapted to receive heat, said side comprising a yielding marginal portion and a contact panel, the contact panel projecting only slightly from the marginal portion and having its corners rounded, and a portion connecting the panel and margin, the panel and margin being in different planes.

2. A water reservoir for ranges having a contact panel projecting from one of its sides, said panel being formed integral with said side, the metal between said panel and side piece being in the form of an ogee curve.

The combination with a. range, of a water reservoir having one side adapted to be held in contact with said range, a housing for said reservoir, the bottom of said housing being formed of sheet metal, a cam carried by said range, a rock shaft carried by the bottom of said housing and cooperating with said cam, and a stiffening member formed of an integral part of the bottom of said housing, said rock shaft passing through said stiffening member.

' Intestimony whereof, I have hereunto set my hand and aflixed my seal in the presence of the two subscribing witnesses.
